Weak truck

When accelerating my truck it runs OK but when I get up to speed and get low RPM running the truck starts shimmering. It’s not throwing any codes and I’m lost. I’m trying to figure out what to do to it. Can someone please help?

Are you experiencing torque converter shudder from the transmission?

I am not sure, but I don’t think so. Just seems to be weak sometimes when I start to take off.

Would it throw a code if there was nothing wrong with the torque converter

The first step is always to read the codes. Without codes, all anyone can do is guess.

It is very unlikely to be torque converter shudder.
